Ok so if I just wanted to run my FTC robot with 4 wheels on a tank drive setup (Left Motors move together, Right motors move together) and all motors stop when I let go of the controller, how would I make that code?? I am very new to this program b/c I used to use labview so if anyone has this basic code so I can practice w/my robot that would be greatly appreciated. If you need some more info, I am using four 12v motors for the drive (2 dc motors), two 12v motors for my grabbing arm, and they are connected by two Hitechnic motor controls. The four drive wheels are all on the same control board while the arm is on the other one. Also, the first control board connects to the second one; both of which connect into S1 port of the nxt brick. Thank you once again to whoever can help me out here!

I would recommend opening RobotC and selecting <File-Open Sample Program>.
You will find a directory for FIRST Tech Challenge with several examples - a couple of them do exactly this!
